PIU's A. ANLAUF AND FRANZ J. ANLAUF, or CURTIN, OREGON.

LOGGING-BUNK.

Application filed December 2, 1911.

T o all, whom it may concern:

Be it known that we, PIUS A. ANLAUF and FRANZ J. ANLAUF, citizens of theUnited States, residing at Curtin, in the county of Douglas, State ofOregon, have invented certain new and useful Improvements inLogging-Brinks; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in logging bunks, and has for itsobject to produce a device of this character adapted for applicationupon logging wagons or cars, the same being provided with adjustablechock blocks for supporting the logs upon the car or wagon.

A further object of the invention is to produce a device of thischaracter so formed as to prevent accumulation of chips, dirt or barkthereon, whereby the logs are prevented from moving longitudinally,which is common in other devices of this character.

lVth these and other objects in view, the invention consists in certainnovel features o-f construction, combination and arrangement of parts aswill be hereinafter fully described and claimed.

In the drawings: Figure 1 is a side elevation of the device. Fig. 2 is avertical sectional view on the line 2-2 of Fig. 1. Fig. 3 is a detailperspective view of one of the chock blocks, the locking pin beingremoved. Fig. 4 is a perspective View of one of the lockingv pins.

Referring to the drawing, the numeral 1 designates the bolster, the sameconsisting of a base 2, said base being provided with perforations 3,and by which the bolster may be bolted to the car or wagon. Formedintegral with the base 2, and extending longitudinally thereof is avert-ical web 4, said web being provided at its opposite ends andadjacent the upper edge thereof, with a plurality7 of alinedperforations 5, said perforations being tapered axially, the purpose ofwhich will hereinafter be described.

A pair of chock blocks 6 is provided, each consisting of side plates 7,and a central spacing plate 8, the plate 8 being less in length than theplates 7 to produce a groove 9 for the reception of the web 4, wherebythe blocks are adapted for sliding adjustment on said web. The plates 7and 8 are formed with beveled edges 10, said edges Specification ofLetters Patent.

extending throughout the length of those portions of the plates whichextend beyond the upper edge of the web 4. By providing the bevelededges 10 the plates 7 and S are thus formed with vertical edges 11,whereby upon reversal of the blocks the vertical edges are confronting,thus adapting the device for use in connection with squared material,the normal position of the blocks 6 being as shown in Fig. 1, whereinthe beveled edges 10 are confronting for holding the logs.

Formed near the lower ends of the plates 7 are perforations 12 and 13,said perforations being tapered axially, and arranged in registeredrelation,- the perforations-13 being slightly less in diameter than theperforations 1Q, whereby the tapered shank .14 of the locking pin 15frictionally engages said perforations. The outer ends 16 of the pinsare disposed at right angles to the shanks 14, the weight of the samecausing said ends to normally hang downwardly, so that the projections17 carried by the pins 15 may swing in the slots 1S formed between oneside of one of the plates 7 and the U-shaped bracket 19, the ends ofsaid brackets being rigidly connected to the plates 7 Each of thebrackets 19 are formed with concaved recesses 20 and in which the shanksof the pins 15 rest.

Pivotally connected near the upper ends of the blocks 6 are loops 91,said loops being for the purpose of securing the ends of a binding chainor rope (not shown) for securing the piled logs, when necessary, and theload is too great to be held against accidental displacement by theblocks. Similarly connected loops 22 are provided, and serve to preventloss of the blocks when one of the same is removed when unloading thelogs, a rope or chain (not shown) having one of its ends attached to theloops, and its other end to the bottom of the wagon or car. To adjustthe blocks 6 for different size loads, it is only necessary that thepins 15 be swung into the position as shown in dotted lines in Fig. 1,whereupon the projections 17 thereon will be in a position to bedisengaged from the slots 1S, thus permitting withdrawal of the pins 15so that the blocks 6 may be moved toward or away from each other and theperforations 12 and 13 of the plates 7 register with any of theperforations 5 formed in the web 4, the pins then being inserted in theregistered perforations and the ends 16 thereof turned downwardly, thuspreventing accidental displacement thereof.

That is claimed is:

l. rlhe combination with a bolster' havinga series of perforationsformed therein, chock blocks slidably mounted on said bolster andprovided with perforations adapted to register with the perforations ofthe bolster, U-shaped brackets secured to the blocks, aslot formed bysaid brackets, locking pins adapted to pass through the registeredperforations, and means carried by the pins for engagement in said slotsto prevent accidental removal of the locking ins. P 2. The combinationwith a ear or wagon, of a bolster comprising a base adapted to besecured to the car or wagon, a longitudinal web formed integral withsaid base, perforations formed in the opposite ends of the web, chockblocks provided with grooves adapted to receive the web, whereby saidblocks are adapted for sliding movement Copies of this patent may beobtained for ve cents each, by addressing the Commissioner of Patents,

toward or away from each other upon the web, perforations formed in theblocks and adapted to register with any one of the perforations of theweb, U-shaped brackets cured to the blocks and having concaved recesses,slots formed between the brackets and blocks, locking pins adapted topass through the registered perforations and rest in said recesses, theouter ends of said pins being bent at right angles to their shanks,projections carried by the shanks of the pins, said projections beingnormally positioned in the slots to prevent accidental displacement ofthe locking pins, said projections being operable to disengage with saidslots to Withdraw the locking pins.

In testimony whereof, We aflix our signatures in presence of twowitnesses.
